About: Rho Pegasi

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Rho Pegasi, Latinized from ρ Pegasi, is a star in the northern constellation of Pegasus, near the southern constellation boundary with Pisces. This is a probable astrometric binary system, as determined by changes to the proper motion of the visible component. It has a white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.90. The system is located at a distance of approximately 274 light years from the Sun based on parallax, but it is drifting closer with a radial velocity of −10.6 km/s.

  • Rho Pegasi, Latinized from ρ Pegasi, is a star in the northern constellation of Pegasus, near the southern constellation boundary with Pisces. This is a probable astrometric binary system, as determined by changes to the proper motion of the visible component. It has a white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.90. The system is located at a distance of approximately 274 light years from the Sun based on parallax, but it is drifting closer with a radial velocity of −10.6 km/s. This visible component is an A-type main-sequence star with a stellar classification of A1V. The star is 331 million years old and is spinning with a projected rotational velocity of 107 km/s. It has 2.8 times the mass of the Sun and 3.1 times the Sun's radius. The star is radiating 110 times the luminosity of the Sun from its photosphere at an effective temperature of 9,484 K. (en)
  • Rho Pegasi (50 Pegasi) é uma estrela na direção da constelação de Pegasus. Possui uma ascensão reta de 22h 55m 13.62s e uma declinação de +08° 48′ 57.9″. Sua magnitude aparente é igual a 4.93. Considerando sua distância de 282 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.22. Pertence à classe espectral A1V. (pt)
  • Rho Pegasi (ρ Pegasi, förkortat Rho Peg, ρ Peg) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den södra delen av stjärnbilden Pegasus. Den har en skenbar magnitud på 4,90 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 10,5 mas, beräknas den befinna sig på ett avstånd på ca 312 ljusår (ca 96 parsek) från solen. (sv)
